molding latex.?

[Sikk]

Just received my first purchase( un-named company is a major supplier) of molding latex, 1 Qt jar. the latex had a thick skin (1/4") on top and is lumpy, is this normal? should I stir or mix this lumpy mixture? Or is it getting old? Container was sealed well. thanks, Paul

It is old. I would send it back.

thanks guys, I called the supplier and they are sending a new Qt at no charge, thanks for the timely advice, I probably would have eaten this one without knowing and better, paul
